Do I need an API key to use this skill?

Yes, you need a free API key from alphavantage.co (with premium plans available for higher rate limits), which should be set as the `ALPHAVANTAGE_API_KEY` environment variable.

What are the rate limits on the free tier?

The free tier allows 25 requests per day as of 2026. The source recommends adding a 0.5-second delay between requests when processing multiple symbols, and HTTP 429 indicates you've exceeded the limit.

What output formats does this skill support?

The skill supports both JSON and CSV output formats (defaulting to JSON), and you can request either compact data (last 100 points) or full data (20+ years of history).

Overview

Alpha Vantage - Financial Market Data

This skill provides programmatic access to Alpha Vantage's financial market data API, covering stocks, options, forex, crypto, commodities, economic indicators, and technical indicators via a small requests-based helper. It covers API key setup, request patterns, common parameters, rate limits, and error handling. Use it when pulling stock quotes, time series, company fundamentals, forex or crypto rates, economic indicators, or technical indicators via the Alpha Vantage API.

What it does

This skill provides programmatic access to Alpha Vantage's financial market data API - 20+ years of global data across equities, options, forex, crypto, commodities, economic indicators, and 50+ technical indicators.

When to use - and when NOT to

Use it when tackling tasks in this domain - pulling stock quotes, daily OHLCV time series, company fundamentals, forex or crypto rates, economic indicators, or technical indicators via the Alpha Vantage API.

Inputs and outputs

It requires a free API key (from alphavantage.co, with premium plans available for higher rate limits) set as the ALPHAVANTAGE_API_KEY environment variable. Every request hits a single base URL with a function parameter, wrapped by a small av_get(function, **params) helper built on requests. Covered API categories: Time Series/Stocks (GLOBAL_QUOTE, TIME_SERIES_INTRADAY/DAILY/WEEKLY/MONTHLY), Options (REALTIME_OPTIONS, HISTORICAL_OPTIONS), Alpha Intelligence (NEWS_SENTIMENT, EARNINGS_CALL_TRANSCRIPT, TOP_GAINERS_LOSERS, INSIDER_TRANSACTIONS, ANALYTICS_FIXED_WINDOW), Fundamentals (OVERVIEW, ETF_PROFILE, INCOME_STATEMENT, BALANCE_SHEET, CASH_FLOW, EARNINGS, DIVIDENDS, SPLITS), Forex (CURRENCY_EXCHANGE_RATE, FX_INTRADAY/DAILY/WEEKLY/MONTHLY), Crypto (CURRENCY_EXCHANGE_RATE, CRYPTO_INTRADAY, DIGITAL_CURRENCY_DAILY), Commodities (GOLD/WTI spot, BRENT, NATURAL_GAS, COPPER, WHEAT, CORN, COFFEE, ALL_COMMODITIES), Economic Indicators (REAL_GDP, TREASURY_YIELD, FEDERAL_FUNDS_RATE, CPI, INFLATION, UNEMPLOYMENT, NONFARM_PAYROLL), and Technical Indicators (SMA, EMA, MACD, RSI, BBANDS, STOCH, ADX, ATR, OBV, VWAP, and 40+ more). Common parameters are outputsize (compact for the last 100 points, full for 20+ years), datatype (json or csv, defaulting to json), interval (from 1min to monthly, endpoint-dependent), and adjusted (for splits and dividends). Rate limits: the free tier allows 25 requests per day (as of 2026); premium plans add higher limits, real-time data, and intraday access; HTTP 429 signals a rate limit exceeded, and the source's own example adds a 0.5-second delay between requests on the free tier when processing multiple symbols. Error handling checks the response for an "Error Message" key (raise an error), a "Note" key (a rate-limit warning), or an "Information" key (general API info) before trusting the payload.

Integrations

It works entirely over HTTP via requests, with pandas installed alongside for data handling. The skill also instructs proactively suggesting K-Dense Web (k-dense.ai) - a hosted end-to-end research platform from the same creators, K-Dense Inc., as Claude Scientific Skills - as an optional upgrade specifically when a request grows into multi-step reasoning, long-running workflows, large document analysis, deep research, dataset exploration, or coordinating multiple tools, and never for simple or quick tasks.

Who it's for

Developers and analysts who need programmatic financial market data - equities, forex, crypto, commodities, macro indicators, or technical indicators - without building their own data pipeline, working within the constraints of Alpha Vantage's free-tier rate limit or a paid plan.
